488	proxy_next_upstream_action to distinguish different network actions	Shafreeck Sea		"add proxy_next_upstream_action

The directive ""proxy_next_upstream error timeout"" takes effect on three network actions: connection, send and recieve. In practice ,we realy want to try next upstream according to in which actions we are. For example, I do not want to try next upstream if some error occurs or timed out when recieving response from upstream, otherwise it maybe duplicate my request .
so the proxy_next_upstream_action is involved to address this problem , the directive takes one or more parameter : conn, send, recv which indicates whether we should try next upstream.
Usage:
proxy_next_upstream error timeout;
proxy_next_upstream_action conn;
Tring next upstream if error or timed out on connection."	enhancement	closed	minor		nginx-module	1.5.x	fixed	proxy_next_upstream			1.2.7
